ELECTBC SEALING DEVICE.

Application filed December 10, 1920. Serial No. 429,717.

To all whom t may concern.'

Be it known that l., CHARLES BARRETT,

a citizen of the United States, and a resident of the city, county, and State of N ew l o rk, have invented certain new and useful lmpi'ovenients in lill ectric Sealing levices, of

which the following is a specification.

My present invention relates to devices for applyingsealing wai: oi' a similar sub )stance to envelopes, packages and the like,

and for impressing on said substance while still plastic,

sealing die. The

a seal by means of a suitable object of the invention is to provide a strong device of this character,

which will be simple inv eflicient in operati toget out of orde construction and on, and which is not liable r very readily.

cal section taken on line and 7 are horizontal sec-tions taken on lines -5, *t5- 6, and 7-7 iespectively of Fig. 2.

My improved s framev consisting ealing device comprises a of a base 10, and two standards or uprights 11 connected .at their upper portions by a transverse top or cross member 12. vided with a cir rlhe base is preferably procular opening 10 (Figs.

4 and 7), and with the cross member 12 is connected rigidly, 13 extending into handle 111 which up and down on said at its center, a guide rod a recess 14C formed in a latter is adapted to slide guide rod, and is held in its uppermost position by means of spring 15 coiled around s are also secured aid rod. To the handle lll rigidly two laterally-arranged rods 16 extending loosely through suitable openings in the top member 12 and having their lowerends rigidly connected to the top or cross m prising parallel side ember 17 of a carrier conimembers 18 which are adapted to move lengthwise of the standards 11, adjacent the inside thereof.

To the standards 11 is secured rigidly, as

by screws 19, 20 normally clos a sealing wax receptacle ed by a valve or plug 2l carried by an upwardly-extending rod 22 the upper end of which is rigidly connected with the rear end of a transverse plate 23 resting on the top member 12 and having at its forward end a knob 24. The plate 23 is provided with suitable holes or sockets to allow for free movement of the rods 13 and 16, and it is normally held in contact with the top member 12 by the action of the spring 15, the latter bearing with one of its ends against the plate 23 and with the other end against the handle 14e. The wall of the receptacle 20 preferably contains an electricl heating element of any approved construction, indicated at 25, to which current is supplied by means of wires 26, extending through suitable holes 27, and a connector plug 28 of well-known character 1).

To the lower ends of the carrier members 18 are secured pivotally, as by pins 29, the side members 30 of a swinging frame, these side members being connected by a transverse member 31, to which is secured rigidly the die or seal 32. The pins 29 extend through vertical slots 33 in the standards 11 and are guided therein. @ne of the side members 30 is extended beyond its pivot, and this extension cairies a pin 34 which also extends into the corresponding slot 33 and is guided therein. This slot has at its upper end a curved extension 33 into which the pin 311 slides when it reaches the upper end of the slot 33. The slot 33 on the other side may be a simple vertical slot without extension.

The standards 11 carry, rigidly secured thereto, outwardly and downwardly-extending brackets 35 the lower ends of which form pivots for a rod 36 which latter carries two downwardly-extending arms or links 37. These arms serve to support pivotally at their lower ends a moistening roller 38, covered with any suitable absorbent mate rial, and urged inward (toward the frame) by a spring 39, the ends of which are secured 'to the brackets 35, while its central portion bears against a pin 410 extending from one arm 37 to the other and secured thereto intermediate their ends (Fig 1). Stops 35 on` the brackets 35 limit the inward movement of the arms 37 and therefore of the roller 38.

The operation of the device is, briefly described, as follows: After the receptacle 20 has received a supply-of sealing wax or the like, and this material has been brought to the desired liquid or viscous condition, the device is placed on the article, such as a letter or package, which it is desired to seal, in such a manner that the opening ,10 in the base is above the place where the seal is to be applied.v The operator thendepiesses the knob 24, thereby lifting vthe valve i'od22 and the plug 21, and allowing the sealing wai; to flow out oit' tlieoutlet 21 into the surface oi the article to be sealed. As As oon as the required amount or sealing materialy has been deposited, he releases the pressure on the knob 24, and the spring will then re turn Ythe plate 23 and connected parts to their normal position with the plug 21 clos'- ing the outlet lie then depresses thev handle 14 bringing it from the position shown by full lines Figs. l, 2 and 4 and by dot andvdash lines in 3 tothat shown .in full lines in F ig. 3. This movementwill cause the pins 29 to travel down in the ver tical slots 33; the pin 34 will-first move alongthe curved slot` portion 33', and the combined movement of.` the pins 29 and 34 will cause thedie-carrying traine 30, 31 to swingfrom its normal position shown in Figs.1,v2and 4 (and also in dot and dash lines in Fig. 3) to a vertical position, in which the side members 30 extend parallel to,and form a combination of, the carrier members 18. During this swinging movement the die 32 will pass in` contact witlrthe moistening vroller 38 and its surl'ace will thus be thoroughly moistened,lthe spring 39 insuringclose contact between thedie and the roller. A'fiirther downward pushfon the handle 14 will then'carry the die 32 down with the pin 34 now traveling inthe vertical slot 33 untillit is pressed into tliesealing wax previouslydeposited in position Fig. 3, thusii'naking the desired impression therein, the previous moistening of the die preventy ing sticking of the wax to the dies surface.

After lthe impression has been made, the operator releases his hold on the handle,v and the `pa-rtsof the device will return to their original position shown in Figs. 1, 2 and 4,A under the action oi'" the spring 15.-

' It is to be understood that the construc. tion illustrated in the drawings and described above represents only thepreferred form of my invention, and that .various mod-f ilications maybe made without departing from Athe spirit of my invention as vdefined in the appended claims.
